The pack rat or packrat, also called the wood rat or trade rat, is a rodent. It is one of many species in the genusNeotoma. Very often, people mean the bushy-tailed woodrat (Neotoma cinerea). Packrats are common in the deserts and highlands of the western United States and northern Mexico. They are smaller than a usual (Old World) rat, and usually have long, sometimes bushy tails. They are also not related to the rat, other than also being a rodent.
